A TTORNEX Patented Jan. 9, 1 940 UNIT En STAT- Es PATENT. orFicE Application March 22.

This invention relates to improvements invalves or control devices of the character adapt? ed for selective fluid distribution to a plurality of associated utilizing means.

5 For example, valves of the character stated maybe employed with a pump in apparatus for cleaning engine crank cases and the like, wherein the valve is adjusted to selectively connect the pump in fluid circulation with a plurality of cone 1. duits having to do with the flow of the cleansing fluid in relation to the crank case, etc."

I contemplate providing a valve of simple and inexpensive construction which may be readily applied to a multiple circuit fluid system for cirtlie'valve.

The invention further has in view the provision culati'on control through simple adjustment of of internal annular supply and return means embodying a pair of movable channels or ports for I I selectively establishing fluid communication between the supply and return means and a pair or plurality of pairsof distribution means, whereby the valve'is readily applicable to the purposes above stated.

I Additional objects and advantages of my invention will become apparent from the following description taken in connection with the accompanying drawings, wherein: Y Fig. l is a diagrammatic elevational view showa ing an application of my invention; I

Fig. 2 is an enlarged sectional view-showing one I embodiment of the'valve of my invention;

Fig. 3 is a reduced cross-section taken on line III-III of Fig. 2;

ll Fig. 4 is a view similar to Fig. 2, showing a modification;

Fig.5 is a cross-section taken on the broken line V-V of Fig. 4; and Y Fig. 6 is a partial sectional 'view similar to Fig. 2, showing a further modification.

l arly to the form of my invention illustrated in Figs. 2 and 3, the valve generally consists of a body portion including front and rear stationary members or disks Sand 6 respectively, and a separate intermediate rotatable member or disk 1. While the members '5 and 6 are shown and are preferred as separate members for purposes of manufacture and assembly, it is intended that .they may be embodied in a single member if desired. r

8 designates an operating shaft or stem'extending centrally through said members, said stem beingrotatabiy mounted in members 5 and 6, and

having engagement by key section 9 with the the'axis of rotation of the valve. Formed in the centric-grooves in the members registering to form a pair of completely annular concentric 'facesjll and ll of the members 5 and I, located Referring to the drawings, and more particustationary I vsnvl 9 George la sm-rl ttlllll lhrla. I l I ms, Serial is. 191,420

movable member "1 for rotating the same between and relatively to said stationary members.

- At the front of the valve, the stem l is shoul-' dered as at In for engagement with the member I 5, and is provided with an operating handle or 1' I arm [2 secured theretoas by a pinjor key.

A reduced rear portion of the stem 8 projects through and beyond the member 6; and has an abutment washer It, for a conical sp ing ll. Said spring bears against the rear face of member 6 and v:is adjustable through movement of the washer by nuts I! on-the rear terminal threaded portion ii of the stern, for proper bearing pressure to retain the members i, 6 and 'l in proper contact,- while permitting rotation of the said member'l. Frontmemberji and the rotatable member 1 are. each provided with flat bearing faces I I and I8 respectively, which faces extend normally to face I! of member 5 are a pair of concentric open grooves 19 and III. Similarly, the face ll of member I is formed with a complemental pair of open concentric grooves 2| and 22, said confluidsupply passages 23 and 24..

25 designates a plurality oi spaced concentric sealing or packing rings annularly seating in both passages 23 and 24.

The front member 5 is further provided with a pair of fluid passages 28 and 21 extendingradially inward irom the periphery of said member. One of said passages, as for example, passage 26, communicates with annular fluid passage 23 by a passage 28, and passage 2'I- communicates with the other annular passage 24 bya passage 28. Passages 28 and 21 are adapted for connection, as by'conduits 30 and 3|, with a fluid pump or the like", as in Fig. 1, said conduits 30 and ll being connected with the discharge and inlet sides of the pump respectively. 7 v

Rear valvemember or disk I is formed with an annular series of through ports or distributing passages arranged in diametric pairs, as in Fig.

3, said pairslof ports being designated 33-,

passages are disposed to be rotated by member ll;

I in an annular path coincident with-the said annular series of ports in member 6.

Passage "extends through the member 1 for communication with annular passage 24, and

recessed to receive said gasket, which, under the passage 39 communicates with annular passage 23 through connecting passages 4| and 42.

Suitable means are provided for sealing the communication between passages 39-40 and the series of ports in member 6. For example, the said ports in member 6 may be formed with surrounding" seats 43 in the plane of the contacting faces of members 6 and I, and passages 39 and 40 may be provided with reciprocable valves or sealing bushings 44 having springs 45 for normally urging said bushings into contact with the seats 43v upon the passages 39-40 coming into register with any of the diametric pairs of ports in valve member 8.

Spring-actuated bushings 44 also function to determine and'retain the register of passages 39-40 of rotatable member 1 with a selected pair of ports in the member 6.

It is therefore seen that upon Hence, in a multiple system wherebyit is desired to pass a body of fluid through a plurality of circuits, conduits and 3| being connected v with the discharge and inlet sides of a fluid pump 1 respectively, and connecting the pairs of ports 3334,.3536 and 3l-38 in'the desired plural fluid circuits, the valve of my invention will readily establish a circulationof a body of supplied fluid with the pump and that particular circuit connected between any selected pair of ports.

Such a use of the valve dicated in- Fig. 1, wherein said valveis connected by a plurality of conduits, to a meter," filter, trap, etc. for circulating a flushing oil for cleaning an engine'crank case, the same being shown'herein merely byway of illustration, since the cleaning apparatus forms no part of the present invention, and is thesubiect matter of a separate application of even; date, Serial No.

Attention is called to ,the'fact-that-my valve is entirely reversible, whereby-I am fenabled to reverse the connection of portsvlljand 21 with a circuit connecting any .-off the;'-:pairs of ports 33-44, 36 or 31-38 merelwbyrotating the? member I through 180-degrees. This is of con siderable advantage where a reversing circulation of fluid is desired.

Fig. 6 illustrates a modified form of my invention, wherein the pair of'annular fluid passages23 and 24 are formed entirely in the member 5, or more specifically, in the face [1 thereof.

In this form, the contacting face ll of rotatable member I is formed with a pair of concentricprojecting annular'rib portions a and b having tapered cross-section for respectively rotating in sealing engagement with the passages 23 and 24.

'Ihe rotatable member I has passages 38-- .42 and respectively formed therein as before, the passages 42 and 40 opening through the portions a and b respectively for communication with annular passages 23 and 24.

Fig. 6 also illustrates a modified form of seal- ..ing means between the passages of member 1 rotation of the a member I by handle l2-and stem 8, any of the of my invention is inand the annular series of ports in member 6,

consisting of"*an annular perforate gasket 44a recessed in and secured to member 6 as by screws d. The meeting face of member I is likewise tact to prevent the escape of fluid therebetween,

and are held by a rear spring Hm adjustable, for proper tension by washer l3a on the rearward threaded terminal lia of .stem 80., as before.

23a and 24a designate spaced concentric annular passages formed by complemental grooves in the contacting faces Ila and IBa of members 5a andfla. respectively, or more particularly, in the inclined portions 5b and 1b thereof.

Member 6a is provided with the series of diametric pairs of ports in the portion 6b thereof, said ports being designated 33a,-34a, 35a- 36a, and 31G-38ll, and member Ia has a single pair of diametric ports 39a and 400. respectively extending from annular passages 23a and 24a outwardly for register with the annular series of ports in said member 6a.

The member 5a is preferably hollow and has "apair of conduits 26a and 21a for passage of fluid to. and from the passages 23a and 24a; respectively, said conduits being connected with outer conduits 30a and Ma for connection with a pump or other means as before.

designates a front plate threaded into member 5a, and has an index ring 46 thereon, which ring has a series of radialnotches 41 therein for engagement by the operating handle I 2a for proper register of passages 39a and 40a with any of the pairs of ports in the member 8a. Handle a-is pivoted to the stern 8a and has a spring 48. for retaining said handle in the notches of the index ring while permitting disengagement thereof for rotation of the valve.

,Both the disk-type and plug-type construcoperable under high pressures without leakage.

The location of the pairs of distribution ports in members 8 or 60. in a single plane facilitates construction of the valve, and renders the same readily applicable to a plurality of conduit connections without difficulty as to working space.

Since the said distribution ports are disposed in pairs as stated, no dimculty is encountered in making connections with multiple circuits to provide for proper fluid circulation therein. Likewise, the valve of my invention is unlimited as to the number of'pairs of distribution ports, it being only necessary to enlarge the diameter of the valve in accordance with the desired number of ports required so as to maintain a sufllcient spacing therebetween.

The valve may be mounted in any suitable manner, as for example, by attaching the front members 5 or 5a to a supporting panel or frame 49. While the plural conduits connected with the members 6 or 6a will maintain said members a in communication with the said annular 2,180,657 3 stationary, suitable external connecting straps communicating with an independent circulation 50 may be employed to secure the members 6 conduit, one of the stationary members having or 6a to the members I or 50 if desired. a plurality of annular pairs of diametrically op- Varlous changes and modifications are contemplated within the scope of the following claims.
